I got this error message when I was trying to get the package with Unreal Frontend.
ERROR: Failed to copy D:\Program Files\Epic Games\UE_4.19\Engine\Binaries\ThirdParty\NVIDIA\NVaftermath\Win64\GFSDK_Aftermath_Lib.dll to D:\_Project\BWGame_WorkSpace\BWGame\Saved\StagedBuilds\WindowsNoEditor\Engine\Binaries\ThirdParty\NVIDIA\NVaftermath\Win64\GFSDK_Aftermath_Lib.dll
I got the last version of Unreal Engine from the launcher.
Thanks in advance
